Police: Stop tweeting during shootings, manhunts

Authorities want social media to use restraint during crime investigations.

Police in Washington state are asking the public to stop tweeting during shootings and manhunts to avoid accidentally telling the bad guys what officers are doing.

The "TweetSmart" campaign began in late July, but some are calling the effort a step that could lead to censorship.

Social media expert Nancy Korb of the International Association of Chiefs of Police says she's not aware of any post that's led to the injury of a police officer, but she says there've been a few close calls.

She says tweets have interfered with investigations.
